I came across this question in Mathematics Stack Exchange where the OP neglected to specify the type of norms he wants people to help finding. The specification can be made clear by simply adding
1- in front of the word
norms. But that edit is not allowed at the moment due to the minimum character length limit on edits.
I am not sure if the limit is reputation related. In any case, I don't think it should apply to Mathematics Stack Exchange where complex concepts are commonly conveyed with brevity using commonly understood notations and formulas.
What do you think? If you are a Mathematics Stack Exchange user, do you think the minimum character limit on edits should be removed?
